Asymptotic limits, Banach limits, and Cesàro means
C. S. Kubrusly, B. P. Duggal
Every new inner product in a Hilbert space is obtained from the original one by means of a unique positive operator The first part of the paper is a survey on applications of su…

Boundedly Spaced Subsequences and Weak Dynamics
C. S. Kubrusly, P. C. M. Vieira
The purpose of this paper is to characterize weak supercyclicity for Hilbert-space contractions, which is shown to be equivalent to characterizing weak supercyclicity for unitary o…

Weakly Supercyclic Power Bounded Operators of Class C_{1.}
C. S. Kubrusly, B. P. Duggal
There is no supercyclic power bounded operator of class There exist, however, weakly l-sequentially supercyclic unitary operators We show that if i…
